Eclipse Champion and multiple Grade I winning Thoroughbred mare Hidden Lake has died.

The 23-year-old daughter of Quiet American was euthanized Sept. 29 at Old Friends, the Thoroughbred retirement farm in Georgetown, Kentucky, where she had been pensioned since 2009. Michael Blowen, founder and president of Old Friends, attributed her death to infirmities of old age.

Owned and campaigned by Robert N. Clay and Tracy Farmer for three seasons, Hidden Lake broke her maiden at Del Mar as a 2-year-old and was stakes placed throughout her 3-year-old year. But it was during her 4-year-old season, after moving to the East Coast, that the mare truly made her mark.

In 1997 Hidden Lake captured four graded stakes, three of them Grade I races, including the Hempstead Handicap at Belmont and the spectacular Go for Wand at Saratoga, a formidable performance after which she nearly collapsed from heat exhaustion
